A team led by the Southwest Research Institute (SwRI) has created a model of the early impacts on Venus to explain how Earth's sister planet maintained a young surface despite not having plate tectonics.
Image 1. Topography and SAR image of the research area on Venus. Color indicates altitudes, measured relative to the planet's mean radius from Magellan's reticulated altitude data. The X and Y axes represent geographic longitude and latitude of the planet. From the study.

A new analysis of data from the XNUMXs has proven that volcanoes are still erupting on Venus today

The article "Surface changes observed on a volcano in Venus during the Magellan mission" describes the analysis of the observations in which surface changes were discovered on the Sif Mons volcano during the Magellan spacecraft mission in 1991-1994
